-' SAFETY-STOP FOR MINE-CABS.

To all whom it may concern: Be it known that we, HENRY H. HERBOL and CHARLES HEGNER, citizens of the United States, HENRY H. HERBOLD residing at Thayer, Oregon county, Missouri, and CHARLES HEGNER at Cainesville, in the county of Harrison and State of Missouri, have invented certain new and useful I1n provements in Safety-Stops forMine-Cars, of which the following ,is a specification.

This invention relates to that class of stop devices for mine cars which are designed to prevent the cars from being precipitated Into an open shaft, and it is the object of the invention to provide a simple, reliable and eflicient device of this kind.

In order that the invention may be better understood, reference is had to the accompanying drawing, in which- Flgure 1 isan elevation showing the application thereof. Fig. 2 is a cross-section on the line 2'2 ofFig. 1.

Referring specifically to the drawing, 5 denotes a mine-shaft, and 6 is a gallery leading therefrom. In the gallery are laid rails 7 on which. the mine car 8 runs. The stop device is located in the gallery a short distance from Where it opens into the shaft, and it compriss the following parts: To one ofthe rails 7 is pivoted at one of its ends, as indicated at 9, a lever lOwhich extends at its other end for a short distance into the shaft 5, and carries atthe last-mentioned end .a bumping post 11. The lever extends horizontally and is pivoted to swing in a verticalplane. Intermediate its ends, the lever carries an upstanding butlerhorn or' abutment 12 which normally extends v alongside the rail into the'pathgfpthe car wheel so as to engage the are; and stop the car. The lever works in a pit 13 be neath the floor 14 of the gallery, said floor I having an opening 15'through which the lever extends downward at its pivoted end,

into the pit. "The floor also has an opening to accommodate the abutment 12.

Specification of Letters Patent.

Application filed December 15, 1911.

Patented Mar; 5, 1912. Serial'No. 666,008.

To the bottom of the floor I4 is rigidly secured a plate 16 carrying depending rods 17 which extend into the pit and carry a plate 18 at their lower ends. The late 16 has a slot 19 through which the 12 extends- The lever 10 is held against lateral displacement by being located bemay be a V-leaf spring or any other type of spring, and it is fastened at its ends to the lever 10. and the plate 18. "*The'base and head of the rail are recessed on one side as indicated at 21, in which recesses the abutment 12 works, thus bringing the latter di rectly in the path of the car wheel, and mwlgii' ing it impossible for said wheel to pass when the abutment is in elevated position. A

The abutment 12 is normally in elevated position, so that the car cannot run into the shaft 5. When the descendin cage (not shown) strikes the post 11, the iever 10 is swung downward, whereupon the abutment 12 is lowered to release the car and enable,

the latter to be run on the cage, As the cage *5 ascends, thespring 2O pushes the lever up wardly and the abutment is again placed in operative position, ready to sto the nextcar.

The device herein describe complicated parts to get out of order, andit is therefore safe and reliable, and it his, fecthally servesthe purpose for which it is designed. The device can also be plied to the. mouth of the shaft, and itis adapted for all kinds of mine cars.'- j T e drawing shows only one of the rails equipped 'with the device, but it will be an derstood that the other rail maybe similarly equipped.

is devoid of i We claim:

1. A car stop comprising a support, rods depending from the support, a platecarried by the rods, a lever pivoted to swing ii; a

vertical plane between the rods, '2, spr ng plate carried by the rods, a lever plvoted to swingin a vertical plane beneath the support and between the-rods, a spring between the lever and the plate, and an abutment rising from the lever and passing through the slot ofthe support.
